Abstract (en)
[origin: EP1959681A2] An image processing device for processing image data includes: a gray level transforming processing unit which receives input of image data, performs gray level transforming, and outputs image data having all of multiple color information by each pixel being configured of one of the multiple color information; the gray level transforming processing unit further including a first gray value computing unit for computing a first gray value according to the brightness of a pixel of interest which exists in a pixel location of interest; a second gray value computing unit for computing a second gray value by gray value transforming as to the first gray value; and pixel value gray level transforming unit for computing a pixel value subjected to gray level transforming of the pixel of interest, based on the first gray value, the second gray value, and the pixel value of the pixel of interest.
